Ephemeral existence

(Inspired by a chance conversation with an acquaintance at baby's doc) Babies live in the present. They don't remember what you said to them two hours ago and they don't remember to frown at life's impossibilities. They don't fret on missing birthdays and they don't care about forgetting anniversaries. For them their world is NOW and it could translate into a hug now, milk now or pick-me-up-else-I'll- scream now. It's so refreshing to live without any hang-ups of who said what when they actually mean something else. So different to live without continuously being evaluated for your actions, to live in the freedom of thought and action. Why do we build fractious Walls around ourselves? Why must we always conform to 'society'?  Why must we be made topics of conversation if we deviate even a bit from the 'accepted'? Why this hypocrisy?
